[oXygen-user] How do I switch off validation of XSDs that are called by an XML document instance [SEC=UNCLASSIFIED]

Hi George,

Thanks for the reply.  I have made comments to your's below:

I was trying to avoid using relative path names because this means that my XML document instance will have to be in the "EPSGschemas" directory.  Not everyone will have this structure and hence I used full URLs and OASIS Catalogue XML files to point to the local copies of the XSDs. (See below.)

Yes that is right. However, my OASIS Catalogue XML file has the following content.

   <!-- Schema for EPSG namespace -->

    <system
        systemId="urn:x-ogp:spec:schema-xsd:EPSG:0.1:dataset"
        uri="file:///O:/downloads/EPSGschemas/gml3.2.0/EPSG.xsd"/>
    <system
        systemId="http://www.isotc211.org/2005/gml.3.2.1/gml.xsd"
        uri="file:///O:/downloads/EPSGschemas/gml3.2.0/gml/gml.xsd"/>

    <system
        systemId="http://www.isotc211.org/2005/gml.3.2.1/xlink/xlinks.xsd"
        uri="file:///O:/downloads/EPSGschemas/gml3.2.0/xlink/xlinks.xsd"/>

I thought that Oxygen would always use the local files (file:///O:/downloads/EPSGschemas/gml3.2.0/) whenever it saw the schemaLocation value.  Is this true or have I misinterpreted how Oxygen uses OASIS Catalogue XML files?

Today I replaced the schemaLocation values with the three "uri" file values as shown in the content of the catalogue file above.  IE file:///O:/downloads/EPSGschemas/.... The validation still gave me the same errors.

I have now temporarily moved the huge XML file into the EPSGschemas directory and changed the schemaLocation to what you have mentioned above. IE gml3.2.0/...  The validation still gives me the same errors.  Shouldn't this work?

Yes. That is correct.  The schemas have not yet been made public. I have been given a ZIP file containing the XSDs. I unzipped them on my local system. This was part of what I made available to you via the URL below. Because there were no official web site holding this information I used a bogus full URL that I know doesn't exist.  I expected Oxygen to get the local XSDs using the OASIS Catalogue XML file as mentioned above.

Yes as mentioned above.

I don't know why you can validate the file and I can't.  It seems to me that I am using the OASIS catalogue file correctly but there must be some setting that gives me errors and you none.  Could that be right?

Thanks.
